1. The scale factor is just the ratio between their two sides. So, for the first figure we have 3.5-6.5(I think), so that has a distance of 3. And, for the next figure, we have 7-13, which has a side length of 6. Thus, the scale factor is 6/3=2.

P dilated by a factor of  (1/3) about the origin  =   (12, 6) (1/3)  =  (4, 2)

 

Q dilated by a factor of 1/3 about the origin  =  (-9, 15)(1/3)  =   ( -3, 5)
